Description

A Comprehensive Look at an Exploding Technology Data Warehousing-From Planning Through Performance-By Top Experts in the Field For a large and growing list of industries, data warehouses are rapidly becoming a 'must-have' strategic business tool. Yet data warehouses are made up of a complex mix of products and technologies, making it tough to keep up with all the latest strategies, theories, and approaches to design and implementation. Data Warehousing with Informix: Best Practices was created to provide a comprehensive overview of the latest information, with a special focus on Informix-based systems. This single volume presents the most innovative ideas on data warehousing, from the most experienced professionals. The book is organized around four main themes: Warehouse Design and Implementation Hardware, Storage, and Backup The Decision-Support Community Future Trends Whether a data warehousing novice or veteran, you will find a wealth of information and ideas in these essays from best-selling authors and well-known authorities in the technology. The contributors represent a variety of viewpoints, from theorists, to nuts-and-bolts programmers, to project/organizational managers.
